OpenVPN is the default protocol among commercial VPN providers. Its fast, secure, and great for bypassing firewalls in countries like China. Users mostly set OpenVPN to port 443 for this purpose.

OpenVPN-UDP can be used for streaming Netflix, zooming, and everything else that can sacrifice some stability for sheer speed. Its an all-rounder VPN protocol that will meet the needs of most VPN users.

Ikev2/ipsec: Great Protocol For Mobile Users


  • Possibly compromised by the NSA
  • Bad for bypassing firewalls

Internet Key Exchange version 2 is a VPN protocol that is especially popular among mobile users.

It offers very fast connection speeds and uses a MOBIKE protocol to seamlessly deal with the changing of networks. This makes IKEv2 great for mobile VPN users, who frequently switch between cellular data and WiFi networks.

IKEv2 was developed in a collaboration between Microsoft and Cisco, and is a successor to the original IKEv1.

What Is IPSec?

On its own, IKEv2 doesnt provide any encryption. Its focus is on authentication and creating a secure VPN tunnel. Thats why IKEv2 is typically combined with IPSec to form IKEv2/IPSec.

IPSec is a suite of security protocols that uses 256-bit ciphers, such as AES, Camellia or ChaCha20. After IKEv2 has established a secure connection between your device and the VPN server, IPSec encrypts your data for its journey through the tunnel.

IKEv2/IPSec is supported by most VPN services, but unfortunately its code base is closed-source.

The protocol appears secure from the outside, but without the transparency of open-source it is impossible to verify that Microsoft havent built backdoors or other vulnerabilities into it.

NOTE: Linux versions of IKEv2/IPSec are open-source and audits have shown nothing untoward with the protocol. For this reason, the closed-source nature of IKEv2 is less concerning than with other closed-source protocols, such as SSTP.

When to use IKEv2/IPSec:

For Defeating Government Censorship

If you are living or traveling to a country where VPN usage is prohibited or controlled by the government, then you must use a top-grade VPN protocol that can conceal your online identity as well as your Internet activities.

OpenVPN is your best bet since it is commonly integrated with obfuscated servers in certain virtual private network services. But we also suggest experimenting with SSTP if you do not need good connection speed since it surpasses OpenVPNs security. SSL/TLS is also an option.

Difference Between Pptp And L2tp

Here is a quick difference between the two protocols based on multiple factors:

Compatible with all devices i.e. Windows, Mac, Linux, Android, iOS, Routers, etc Also compatible with different devices like Windows, Mac, Android, Linux, iOS, Routers.
Pretty unstable when compared with L2TP, but works with Wi-Fi hotspots Very much stable and works on every device, networks and platform.
It can be used with an in-built client, username and password, and server address It is used on a VPN client, username and password, server address, and pre-shared key.
Security Not much secure because it has basic encryption Very much secure because it completely encrypts your data with strong encryption.

Best VPN Protocol For P2p File Sharing

Which VPN Protocol Has The Best Compatibility With ...

When it comes downloading, use a protocol that offers good security and speed. While PPTP is the fastest protocol, it lacks security as it uses 128-bit encryption. Both L2TP and IKEv2 use 256-bit encryption through IPSec. However, L2TP lags behind when it comes to speeds while IKEv2 is not supported on old platforms. Though not as fast as PPTP or IKEv2, OpenVPN still provides speeds and top-notch security. The 256-bit encryption makes it the best VPN protocol for P2P file sharing. Winner: OpenVPN

VPN Protocol Comparison: Pptp Vs Sstp Vs Openvpn Vs L2tp Vs Ikev2

A VPNs first duty is to protect your privacy, which is why encryption is undoubtedly the most important aspect of any VPN service. And VPN encryption is all about protocols.

Simply put, the extent to which your traffic is protected depends heavily on the VPN protocol youre using. Currently, five popular protocols can be found in most commercial VPN services PPTP, SSTP, OpenVPN, L2TP/IPsec, and IKEv2.

So how do you choose the best VPN protocol for your needs? The answer seems simple enough: you need to compare them. This comparison, however, can be a bit difficult if you dont have a lot of technical expertise.

Wed love to help you out below, youll find a detailed overview of each of the widely used VPN protocols. Our goal is to give you the benefits and drawbacks, as well as advice on when to use or avoid a particular protocol, in a way thats easily understandable.

Keep in mind, though, that VPN encryption is an extremely complex topic. No single article can serve as a crash course on this subject, and some degree of technical understanding is required. If youre making your first steps into the world of VPN technology, we invite you to start with our beginners guide before continuing with this article.

What You Need To Know About Using A VPN In China

Its not exactly easy to test VPNs for China if youre not actually in China. Thats why we rely on several different testers who live in various locations throughout the country.

These team members are constantly testing each VPN to make sure its up and running. They send us the results at regular intervals, allowing us to keep our recommendations up to date.Before we dive into the best VPNs for China, theres one important thing to mention: if youre traveling to China, youll need to download and install your VPN before you arrive.

This is because the Great Firewall blocks all the top VPN websites. If you wait until youre already in the country, youre pretty much out of luck. Also, the Chinese government mostly goes after VPN technology instead of VPN users, and no tourist has ever been penalized for using one.

I also recommend downloading more than one VPN before you travel, in case the first one stops working at some point. Different VPNs work in different regions, and the government might block your VPN at any moment.

If you do have to connect to the backup, go ahead and download a third option too you should always have at least two VPNs ready to go.

Remember: All of the best VPNs have money-back guarantees, so you can get a refund in case one of them suddenly stops working.

Best VPN Protocol For Streaming

Connection speeds and VPN protocols security both go hand in hand. Therefore, you will need to compromise on speed if you want maximum online protection. When you wish to use best VPN for protocol for streaming purpose, nothing comes close to PPTP.

The above-explained VPN protocol offers fastest streaming speeds to its users. On the other hand, PPTP does have the weakest encryption level.

If you want to attain the right balance between speed and security, OpenVPN turns out to be a right choice. It offers both security and reasonable speed coupled with 256-bit military grade encryption. Therefore, you are able to obtain next level security according to your own terms.

Best choice: PPTP

What Is The Fatest VPN Protocol

The Best Free VPN For PC in 2021

If you want to stream at high-speeds, PPTP is the fastest VPN protocol because of its weak encryption. L2TP and IKEv2 are also fast, while OpenVPN and SSTP are slower than other VPN protocols. Connection speeds are closely related to the security provided by your VPN protocol. After all, high-grade encryption requires a lot of processing power and time. As a result, it slows down the performance. Winner: PPTP

What Is A VPN Protocol

Virtual Private Networks and VPN protocols are not the same thing. NordVPN, for example, is a VPN service that lets users choose from a number of different VPN protocols depending on their needs and the device theyre using.

A VPN transmits your online traffic through encrypted tunnels to VPN servers that assign your device a new IP address. VPN protocols are sets of programs and processes that determine how that tunnel is actually formed. Each one is a different solution to the problem of secure, private, and somewhat anonymous internet communication.

No VPN protocol is perfect. Each may have potential vulnerabilities, documented or yet to be discovered, that may or may not compromise your security. Lets delve into each protocols pros and cons.

L2tp/ipsec The Successor Of Pptp

L2TP emerged in 1999 as a successor to PPTP. It was developed by Microsoft and Cisco and represents a mishmash of PPTP and Ciscoss L2F .

However, L2TP itself doesnt encrypt data. So, the encryption part of the equation is left to IPSec . Thats where the name L2TP/IPSec comes from.

How Does The Sstp Protocol Work

Which VPN Protocol Has The Best Compatibility With ...

SSTP works by establishing a secure connection between a VPN client and a VPN server. Basically, the protocol creates a secure tunnel between the client and the server, and all the data and traffic that passes through that tunnel is encrypted.

Like PPTP , SSTP transports PPP traffic, but unlike PPTP it does it through a SSL/TLS channel. Because of that, SSTP offers significantly more security than PPTP since SSL/TLS provides traffic integrity checking, secure key negotiation, and encryption.

Due to the use of SSL/TLS, SSTP servers must be authenticated when a connection is established. SSTP clients can be optionally authenticated too.

What Is The Most Stable VPN Protocol

IKEv2 is an excellent choice when it comes to stability on mobile devices since it can actually resist network changes. Network admins can block it easily, though, since it only uses a few UDP ports.

WireGuard performs very well too, but it only uses UDP ports, so it can be blocked. On the plus side, it uses a ton of ports, so its unlikely that a network admin would block all of them.

OpenVPN , SoftEther, and SSTP handle stability excellently since they can use port 443 .

Whats more, SoftEther does very well too given that it was made based on the idea that it will run 24/7 permanently once its started up. Its code was written in such a way as to prevent both memory leaks and various crashes. Even if something goes wrong, SoftEther is programmed to re-start automatically as fast as possible.

Other stable VPN protocols include OpenVPN , SSTP, and L2TP/IPSec. PPTP is also pretty stable, but keep in mind it can be blocked by firewalls with ease sometimes.

PPTP and L2TP/IPSec are pretty stable too, but its easy to block them you just have to block the ports they use or disable VPN Passthrough for those protocols to prevent the VPN app from communicating with the VPN server.

Our Recommendation: IKEv2, SoftEther , or OpenVPN TCP

What Is The Least Resource

Without a doubt, PPTP is one of the least resource-intensive options simply because it offers such inferior encryption which doesnt eat up a lot of CPU power.

SSTP is normally a better choice, though, because it eats up less resources while also offering decent security all thanks to the fact that its strongly integrated into Windows platforms. If you use a different operating system or device, you could try OpenVPN instead of PPTP since it can optimize its processing power usage.

But we think WireGuard is the perfect choice for any platform because its optimized to efficiently use CPU cores. Also, it has a very small code base , so its very lightweight.

Our Recommendation: WireGuard

What Is The Best VPN Protocol

There is no such thing as the best VPN protocol suitable for everyone. The answer to this question depends on your needs and what you do on the internet. If youre an avid gamer, you probably use VPN for different reasons than someone who watches a lot of TV shows or often works from cafes. To determine the best NordVPN protocol for you, carefully consider what you need most out of your VPN connection.

How Many Types Of VPN Protocols Are There

L2TP/IPSec VPN Protocol vs PPTP – Which One Is Best?

There are 6 different types of VPN protocols that include OpenVPN, WireGuard, IPSec/IKEv2, Secure Socket Tunneling Protocol , Point-to-Point Tunneling Protocol , and L2TP/IPSec.

However, you wont find all of them in modern VPNs. In fact, only a handful are in use and even fewer are the most supported.

The main VPN protocols that are currently used by VPN providers include OpenVPN, IPSec/IKEv2, Wireguard, and SSTP. Point-to-Point Tunneling Protocol , and L2TP/IPSe are outdated protocols.

Rarely Used VPN Protocols

These are VPN protocols only used by a few VPN providers.


SoftEther is also an open-source VPN protocol known for its excellent security and fast speeds. It started as part of a Masters thesis at the University of Tsukuba.

Although it has not gained industry-wide traction, it has already show-cased excellent results on VPN providers that have adopted it.

SoftEther relies on OpenSSL for encryption and authentication. This gives it access to some of the powerful ciphers, including the AES-256 and RSA-4096.

Also, SoftEther tunnels traffic through the TCP port 443 like OpenVPN. This port guarantees that SoftEther traffic wont be blocked easily as it is the port for HTTPS traffic.

This protocol boasts one of the best connection speeds. It has a built-in Network address translation traversal and an embedded dynamic DNS.

It also supports data compression, and priority is given to VoIP due to the quality of service.

Only two commercial VPNs offer SoftEther protocol Hide.me and CactusVPN. Unlike other protocols, it is not natively supported by computing platforms.


The Best Out Of The Three

Identifying the best protocol primarily depends on the needs of the users. A VPN is used to safeguard privacy, which is the key aspect of a VPN service. The overall performance of a VPN-enabled web traffic protection depends on the type of protocol used. Most of the experts recommend OpenVPN protocol. It is faster, reliable, and secure. Its cross-compatibility on multiple devices and OS makes it a preferred protocol among VPN users. However, OpenVPN requires a third-party application to function. In such cases many turn to IKEv2 or L2TP. Security, speed, connectivity, and reliability are the key factors that determine the performance of a VPN protocol. The availability of the protocol on different OS or devices also matters.

Virtualization of Ethernet devices is the key of the SoftEther VPN architecture. SoftEther VPN virtualizes Ethernet devices in order to realize a flexible virtual private network for both remote-access VPN and site-to-site VPN. SoftEther VPN implements the Virtual Network Adapter program as a software-emulated traditional Ethernet network adapter. SoftEther VPN implements the Virtual Ethernet Switch program as a software-emulated traditional Ethernet switch. SoftEther VPN implements VPN Session as a software-emulated Ethernet cable between the network adapter and the switch.

You can create one or many Virtual Hub with SoftEther VPN on your server computer. This server computer will become a VPN server, which accepts VPN connection requests from VPN client computers.

You can create one or many Virtual Network Adapter with SoftEther VPN on your client computer. This client computer will become a VPN client, which establishes a VPN connections to the Virtual Hub on the VPN server.

You can establish VPN sessions, as called ‘VPN tunnels’, between VPN clients and VPN servers. A VPN session is the virtualized network cable. A VPN session is realized over a TCP/IP connection. The signals through the VPN session is encrypted by SSL. Therefore, you can safely establish a VPN session beyond the Internet. A VPN session is established by SoftEther VPN’s “VPN over HTTPS” technology. It means that SoftEther VPN can create a VPN connection beyond any kinds of firewalls and NATs.
